Report #3129
[agent\_craft] Agent attempts to simulate code execution or trace complex logic purely through text reasoning, leading to hallucinated states
Externalize state tracking and logic evaluation to code execution \(REPL/sandbox\) as soon as the operation involves more than two steps of mutation or precise arithmetic/string manipulation.
Journey Context:
LLMs are bad at simulating state changes \(e.g., 'if I update this array, then map over it...'\). They will lose track. The fix is to write a script, execute it, and read the stdout. Tradeoff: tool execution takes time and sandbox setup, but guarantees deterministic state. Never reason about code state when you can just run it.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
